Nautilus Lifeline Work In Coz?

[NDL_Diver]

Don't overlook the obvious - one of the BEST ways to make sure the boat doesn't forget you is to make friendly conversation with the captain and the DM on the way out, and then have a large SMB inflated if you surface away from the boat. Knowing a few words in spanish doesn't hurt either. It's hard to forget someone who makes a good impression. Bonus points for starting a juicy story just before the dive and leaving them hanging until you get back.

Also dive with small group size helps. We dive six pac boats and missing a diver or 2 is obvious. Diving a boat with 16 or 20 people and one less diver can happen.
We carry a SMB, mirror and flashlight. On really remote or sites in North Cozumel I carry my Nautilus Radio ver 1 that has a full marine radio. They don't make them anymore and I just had it serviced.

The PLBs and such are certainly useful kit and yes a few divers over the years have had problems turning up missing. But, most of the regular dive sites are popular and there are boats all over. I have been asked upon surfacing away from my group due, to the DM having to tend newer divers and giving me the thumbs up to continue, asked by several boats where I belong and once was picked up and taken back to my boat during SI.

If you stay with your guide or in sight of them and also importantly carry a standard size DSMB and deploy it if separated there will be boats all over you trying to pick you up if you are far from yours (say the captain had an issue with another group). Most likely, about 96% of the time, with your DM or not, as soon as your head pops up you will see your captain headed to you or is already there. Getting left to sea in Cozumel, really is less likely than a meteor hitting you on your head during happy hour after dive.

I have been on several liveaboards that provide (free loan) Nautilus Lifeline or similar Personal AIS Beacon (PAB, not PLB) to the divers or DMs to make sure they could launch MOB if they were lost at sea:
Amira (Raja Ampat & Forgotten Islands)
Argo / Undersea Hunter (Cocos)
Ferox (Malpelo)
Galapagos Master
Infiniti (Visayas & Tubbataha)
Maldives Aggresor II
Mermaid I & II (Raja Ampat & Komodo)
Nautilus Undersea (Socorro)
Nautilus Belle Amie (Socorro)
Palau Aggressor
Red Sea Aggressor I
Rock Island Aggressor (Palau)
Spoilsport (Great Barrier Reefs)

I carry one to the liveaboards that don’t issue PAB to divers (Blue Manta & White Manta for example) and test it before cruising to see if MOB signal pops up on their AIS monitors and sounds the alarms when the red button is pressed.

That's great and a lot more necessary for a liveaboard in the open sea.

When did you have your nautilus serviced? what was done? I contacted them around 7 months ago and they said they do not service it anymore so I took it upon myself to figure out how to replace battery.

It was about that time ago and they said all they can do was battery replacement (no other parts) but would do a functional test. Maybe I was one of the last?

How do you access the battery?
What type of battery was it?
Would appreciate any insight for next replacement.
You can PM me if you want. Also any pics by chance?

AFAIK I got mine (gen.2) without batteries and you are suppose to unscrew the lid and insert batteries - as simple as with a torch. Is it any different with the gen.1? What’s the challenge here?

Yes, you were probably one of the last. What they used to do was replace the top cap also with the battery change so now they are out of parts. They told me it was a special battery also and they had no more parts for the original unit. I did a lot of searching and found same battery. You can check out the thread I did on the disassembly here on scubaboard. I show how I pulled the unit apart, where to buy the battery. You will also have to change wires on the battery to be the same as the original ( easy to do). I couldnt find anyone else who had done this battery swap and nautilus would not help me with any info doing it myself either.
